CVE-2009-4536 is a vulnerability of currently unknown severity. drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1385.. EPSS estimates a 5.23% chance of exploitation in the next 30 days.
